Application -filed May'lO, 1920. SeriaINo. 380,162.-

posting ledger racks and theobject of the invention is to provide meansin' a ledger rack which holds'the ledger'in the normal position forposting which will'allow of the ledger being droppedto the" horizontalor fully open position-to permit-inspection of the posted leaf and itconsists essentially of the arrangement and'construction of parts ashereinafter more particularly" explained. Figure 1 is a perspectiveviewof our ledger rack showing the ledger by dotted lines in the postingposition.-

Fig. 2, is a sectional View through the ledger rack showing theretreating side by 'dotted lines in the retreated position and by fulllines in the normal position.

Fig. 3. is an enlarged detail of the arms 7 and adjacent parts.

In the drawings like characters of reference indicate correspondingparts in the various figures.

1 indicates the base frame comprising the cross members 1 and 1 andlongitudinal connecting members 1 and 1 The cross members 1 and 1 at oneend are turned upward andinclined inwardly at 1 and 1', the upperportions of the portions 1 and l 'beingturned outwardly at 1 and 1 Theportions 1 and 1 are turned-baokwardly upon themselves at 1 and 1 suchportions being connected together by a longitudinal bar 1". The portions1 and 1 extend downwardly in an inclined direction to 1 and 1 from whichthey extend vertically at 1 and 1 and are provided with horizontalextensions 1 and 1 extending over the portions 1 and 1, the extreme endsof the portions 1 and 1 being turned upward at 1 and 1 in proximity tothe opposite to the portions-1 and 1 The portions3 and-3 are connectedat their lower ends by hinges?) and 3* to the upturned ends 1 and 1 Theupper ends of the portions 3 and are turned back upon themselves at 3-and 3 corresponding to the structure shown at l and 1 the portions 3 and3 being connected together by a longitudinal bar 8 The outwardlyextending ends of the bars 1* and 1 protruding beyond the upturnedportions 1 and 1 are'provided :with hinges 3 and 3.

' lan'd 5 indicate divided struts formed respectively by the portions 4*and 4 and 5 and 5. The lower ends of the portions 4 and 5 arehingedlyconnected to the hinges 8 and 8". The upper'portions of the portions 4and 5 are hingedly connected to the lowerpo'rtions of the portions 4*and 5 at 4 and 5". The upper ends of the portions 4 and 5 are hingedlyconnected to the lower ends ofthe portions 3 and 3 at 4 and 5 6indicates brackets, the horizontal arms 'of'which are secured to theprotruding ends of the bars'l and 1, the vertical portions being.secured'to the portions 1 and 1 6 indicates a slot which extendsthrough each of the'bars 1 and 1 and horizontal arms of the brackets 6;6 indicates a hinge pin which is secured between the horizontal. arm ofeach bracket 6 and the corresponding portions of the bars l and 1 so asto extend across the slots 6*. 4: indicate slots formed in'each oftheportion's l and 5. 7 indicate curved arms which are pivoted at theirlower ends upon the pin 6? and extend upwardly through the slots 49. Theouter or convex side of the arm is provided with ratchet teeth 7 adaptedto normally engage tudinal bar provided at each end with a slot 8through which the corresponding arm 7 extends, the pins 7 and 7extending to each side of the bar 8. The arm 7 is held in its upwardposition by a suitable spring 9.

When the ledger is to be held in the normal or posting position or theposition shown by dotted lines in. Fig. 1 the arm 7 is in the positionshown particularly in Fig. 2 with the ratchet teeth 7 X engaging theupper end of the slot 4 When it is desired to open the ledger so as tothrow thBfiO-VGI 2 to the horizontal position all that it is neces- Ithe pressure of the springs 9 thereby carrying the teeth 7* out ofengagement with the upper ends of the slots 4: thereby releasing theportions 4- and 5 allowing the divided struts 4: and 5 to break jointand collapse inwardly into the dotted position shown in Fig. 2 andthereby carrying the portions 3 and 3 supporting the ledger cover 2downwardly to the horizontal position.

lVhen it is desired to return the ledger cover to the normal positionall that it is necessary to do is to lift the cover and cross bar 8thereby tending to straighten out the hinge portions 4; and 5 and 4* and5 the curved bar 7 being carried up into engagement by the spring 9 soas to lock the parts in the raised position.

From this description it will be seen that we have devised a very simpledevice whereby the cover of a ledger when held in a posting ledger rackmay be released so as to drop to a horizontal position and thereby fullyopen the ledger for inspection.

What we claim as our invention is.

1. A ledger rack comprising a base frame, a stationary support extendingupwardly from one side of the base frame and against which one cover ofthe ledger is designed to rest, a hinged supporting arm against whichthe other ledger cover is adapted to rest, a divided strut having oneend hingedly connected to the base frame and the opposite end to thesupport and having the divided portions hinged together and adapted tobreak joint when released, and a spring held curved arm pivotallysupported in the base frame and having a toothed convex portion adaptedto engage a suitable portion of the divided strut to hold it in theunbroken position.

2. A ledger rack comprising a base frame, a stationary support extendingupwardly from one side of the base frame and against which one cover ofthe ledger is designed to rest, a hinged supporting arm against whichthe other ledger cover is adapted to rest, a

strut divided into two portions, one portion hinged to the base frameand having a slot therein and the'other portion hinged to the support, ahinge connection between the divided portions of the strut, and a springheld curved arm pivoted in the base frame and extending through the slotof the lower strut portion and having teeth engaging th upper end of theslot.

3. A ledger rack comprising a base frame, a stationary support extendingupwardly from one side of the base frame and against which one cover ofthe ledger is designed to rest, a hinged supporting arm against whichthe other ledger cover is adapted to rest, a pair of strut membersdivided into two portions, one portion of each strut being hingedlyconnected to the base frame and the other portion of each strut hingedlyconnected to the movable ledger support, a hinge connection between thedivided portions of each strut, releasable locking means for holding thestruts in the unbroken position, and means for simultaneously releasingsuch locking means. 7

4:. A ledger rack comprising a base frame,

a stationary support extending upwardly from one side of the base frameand against which the cover of'the ledger is designed to rest, a hingedsupporting arm against which the other ledger cover is adaptedto rest, apair of strut members divided into two portions, one portion of eachstrut being hingedly connected to the base frame and having a slotextending therethroughand the other portion of each strut hingedlyconnected to the movable ledger support, a hinge connection between thedivided portions .of each strut, a. curved arm pivoted in the base frameopposite each strut member and having its upper curved. portionextending through a slot of each lower strut portion, a bar having aslot at each end through which the arms extend, and pins extendingthrough each arm at each side of the bar.
